Nokia is the most targeted platform around the world, according to a survey of mobile developers.

The research, from Evans Data, a specialist in analysis of developer trends, says the situation is slightly different in the US where the focus is on Motorola.

The dominance of Nokia in Europe is no surprise, but the company's platform is now the most popular in Asia too - in fact, everywhere except the US.

The research also shows that 64 per cent of development companies are working on some form of open source application, and half of them plan to introduce location-based information into their apps - except in Latin America, for some reason.
